Check Digit Verification of cas no
The CAS Registry Mumber 6277-13-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,7 and 7 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 6277-13:
(6*6)+(5*2)+(4*7)+(3*7)+(2*1)+(1*3)=100
100 % 10 = 0
So 6277-13-0 is a valid CAS Registry Number.

Efficient synthesis of an A-B-C-tricycle fragment for a structural model of tolyporphin
Hu, Bing C.,Zhou, Wei Y.,Liu, Zu L.,Cai, Chao J.,Xu, Shi C.
experimental part, p. 89 - 100 (2010/11/18)
An efficient stereocontrolled synthesis of an A-B-C-tricycle fragment 7 for a structural model of tolyporphin 3 is described. All the rings were prepared from readily available starting materials. One of the two key steps is a selective ring-opening reaction of the lactone cycle in bicyclolactam-lactone 17 to cyanopyrrolidone 18, which introduces the chirality into synthetic compounds. The other key step is the combination of A ring with B-C-bicycle via a two-time Eschenmoser sulfide contraction. A-B-C-tricycle fragment 7 allows a new approach toward tolypophin compounds and other uroporphinoids.
