Check Digit Verification of cas no

The CAS Registry Mumber 1401236-98-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,1,2,3 and 6 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1401236-98:
(9*1)+(8*4)+(7*0)+(6*1)+(5*2)+(4*3)+(3*6)+(2*9)+(1*8)=113
113 % 10 = 3
So 1401236-98-3 is a valid CAS Registry Number.

Unified approach to catechin hetero-oligomers: First total synthesis of trimer EZ-EG-CA isolated from Ziziphus jujuba

Yano, Takahisa,Ohmori, Ken,Takahashi, Haruko,Kusumi, Takenori,Suzuki, Keisuke

, p. 7685 - 7688 (2013/04/23)

A catechin hetero-trimer isolated from Ziziphus jujuba has been synthesized. Among three constituent monomers, (-)-epiafzelechin and (-)-epigallocatechin were prepared by de novo synthesis. Trimer formation relied on the unified approach to oligomers based on the bromo-capping and the orthogonal activation, reaching the reported structure of the natural product.
