Check Digit Verification of cas no

The CAS Registry Mumber 1228293-50-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,2,9 and 3 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1228293-50:
(9*1)+(8*2)+(7*2)+(6*8)+(5*2)+(4*9)+(3*3)+(2*5)+(1*0)=152
152 % 10 = 2
So 1228293-50-2 is a valid CAS Registry Number.

Synthetic transformations of higher terpenoids. XXI.* preparation of phlomisoic acid and its N-containing derivatives

Mironov,Kharitonov, Yu. V.,Shul'ts,Shakirov,Bagryanskaya, Yu,Tolstikov

experimental part, p. 233 - 241 (2010/09/18)

A method for preparing 15,16-epoxylabda-8(9),13(16),14-trien-18-oic (phlomisoic) acid was proposed. Its structure was confirmed by an XSA. N-containing derivatives of phlomisoic acid that contained amines, hydrazides, and methyl esters of amino acids on the C-18 atom in addition to (2-oxo-2-aminoacetyl)-substituted derivatives of the C-16 methyl ester of phlomisoic acid were prepared.
