Check Digit Verification of cas no

The CAS Registry Mumber 97748-18-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,7,4 and 8 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 97748-18:
(7*9)+(6*7)+(5*7)+(4*4)+(3*8)+(2*1)+(1*8)=190
190 % 10 = 0
So 97748-18-0 is a valid CAS Registry Number.

STERIC EFFECTS OF PHOSPHORUS LIGANDS: cis/trans DISTRIBUTIONS OF W(CO)4L2 PRODUCTS

Ounapu, Lois M.,Mosbo, John A.,Risley, John M.,Storhoff, Bruce N.

, p. 337 - 342 (1980)

The cis/trans product distribution in the reaction of phosphines with W(CO)4(Me2N(CH2)3NMe2) depends on ligand size; the smaller the ligand the greater the cis/trans ratio.The ratios range from 2.9 to 0 for PPh2Me and P(o-Tol)3, respectively.
